Got it and installed it today, seems pretty decent, definitely solid, I trust it a whole lot more than the gravity dropper on my buddy's 6.6 (which is only a 27.6mm seatpost and uses a shim to bring it up to full bore).

The action isn't as smooth as I'd like, it doesn't extend freely all the way, but we'll see if it improves with use or there's something I can do to increase the pressure in the body of the thing.

Make sure you grease the cones that hold the seat adjustment, so you can fully tighten the seat adjustment. If you don't, it will slip when you hit hard on the seat. Once greased, per the instructions on Maverick's website, it hasn't slipped at all.
